Greenland Ice Mass Loss: Jan. 2004 – June 2014

GRACE consists of twin co-orbiting satellites that fly in a near polar orbit separated by a distance of 220 km. GRACE precisely measures the distance between the two spacecraft in order to make detailed measurements of the Earth’s gravitational field. Since its launch in 2002, GRACE has provided a continuous record of changes in the…

Sea level rise of the past 23 years explained

Oceanographer Josh Willis from NASA’s Jet Propulsion Laboratory narrates this video about the causes of sea level rise and how sea level has changed over the last two decades as observed by the Jason series of satellite missions. Source The troubling reasons why NASA is so focused on studying sea level rise

Doubling times of 10, 20 or 40 years yield sea level rise of several meters

According to a new study, sea level rise of several meters might happen faster then previously thought. Based on data from past climate changes, when sea level rose to +5–9 m, including the occurrence of extreme storms – during a time when temperatures were less than 1 ◦C warmer than today, experts warn of similar…

The dangerous silence on climate change and extreme weather

We know that CO2 emissions are bad for climate and subsequently the weather. We know that we have to do something about it, because if not things will turn really ugly with large scale carbon releases (i.e. permafrost melt). However, the current projected changes are bad for many, and because of irreversible changes. So why then is…

Eric Rignot: Observations suggest that ice sheets and glaciers can change faster, sooner and in a stronger way than anticipated

Eric Rignot Professor of Earth system science at the University of California, Irvine, and scientist at NASA’s Jet Propulsion Laboratory was interviewed on sea level rise and projections. Ice sheets and glaciers can change faster, sooner and in a stronger way than anticipated Machens: As an ice sheet expert, how do you see the sea-level projections…

We need to really begin the phase out of CO2 emissions

Think of climate change as a cancer. Your doctor told you that he spotted what appears to be likely a melanoma skin cancer, but he is not 100% sure. Do you wait till the signs become more apparent? The cancer might spread in your body, by that diminishing the chance for survival, or do you ask the…

Climate scientist Piers Sellers on NASA’s satellite observations

https://www.youtube.com/watch?v=2EqJ_WLKIQ8 The view of Earth from orbit was the focus of this What’s New in Aerospace? presentation televised on NASA Television from the Smithsonian National Air and Space Museum in Washington. The program featured Piers Sellers, a climate scientist and former NASA astronaut, taking viewers on a tour of our home planet as never seen…

ScienceCasts: No Turning Back – West Antarctic Glaciers in Irreversible Decline

A 2014 study study led by NASA researchers shows that half-a-dozen key glaciers in the West Antarctic Ice Sheet are in irreversible decline. The melting of these sprawling icy giants will affect global sea levels in the centuries ahead. Read more http://science.nasa.gov/science-news/science-at-nasa/2014/12may_noturningback/

NASA experts explain ice melt in Antarctica

NASA hosted a media teleconference to discuss new research results on the stability of the West Antarctic Ice Sheet and its potential contribution to future sea level rise. The briefing participants are: — Eric Rignot, professor of Earth system science at the University of California, Irvine, and glaciologist at NASA’s Jet Propulsion Laboratory in Pasadena,…
